人地講左thank you之後應該點答佢

You are welcome.thanks!

(after receiving thanks) Don’t worry , no worries, my pleasure
(emphatically: not): by no means, hardly, in no way, not in the least, not in the slightest, not the least bit, not the slightest bit ,
(conventional reply to expression of gratitude): don't mention it, forget it, it's nothing, no problem, that's all right, that's OK, think nothing of it, you're welcome , not at all

最好當然係一個發自內心的微笑。

最簡單就係you are welcome

you are welcome, not at all同no problem都係較casual的
